CHAPTER 1

GENERAL ADMINISTRATION

Records and reports are the bywords in admin-

istration. They are vital in each of the following

department and division functions:

The supervision and assignment of ETs

The upkeep and cleanliness of the spaces

Electronics supply

Allocation of funding

P rocurement of tools; consuma bles (such a s

fuses, bulbs, solder), and equipage items to

replace those lost, expended, or surveyed

Without records and reports, performing these

functions would be impossible.

As an ET2, you will be involved with either creating

or maintaining various administrative records and

reports in addition to maintaining and repairing

electronic equipment.

In this chapter we will discuss some of the reports

that you may be involved in filling out. We will also

cover the different periodicals that will assist you in your

administrative responsibilities.

REPORTS

Reports, like inspections, are a necessary evil to

the working technician. Without reports and a system of

accountability, our job of maintenance and repair would

be impossible. There would be no way to maintain

supply support for our equipment, no way to know what

equipment was on board, in what quantity, or where. In

this section, we will introduce surveys, getting under

way reports, casualty reports, and trouble reports and

logs.

SURVEY

A survey is made and reported when naval property

is (1) condemned as a result of damage, obsolescence,

or deterioration, or (2) acknowledged to be nonexistent

because of loss, theft, or total destruction. Figure 1-1 is

a sample of the Report of Survey, DD Form 200.

You can find more informa tion on DD Form 200 in

NAVSU P P -485, Afl oat Supply Procedu res, loca ted in

your supply department.

1-1

GETTING UNDER WAY REPORT

The electronics material officer (EMO) is normally

responsible for turning in an equipment status report

before getting under way. You may be asked to furnish

information about the equipment in your work center or

about such diverse areas as:

Major systems status

Estimated time of repair (ETR)

Power out and MDS readings from the radars

Power out and receiver sensitivity readings from

communications equipment

This report is usually a locally generated form and

may vary between commands.

CASUALTY REPORT (CASREP)

The CASREP system contains four types of reports:

initial, update, correct, and cancel. CASREPs are not a

substitute for, but are in addition to and complement,

3-M data. You can find information on preparation and

submission of casualty reports in Operational Reports,

NWP 10-1-10 (form erly NWP 7 [RE V. A]).

TROUBLE REPORTS AND LOGS

Trouble reports an d logs ar e locally generated a nd,

if used, are a great help in filling out 3-M documents.

They a re usua lly f i lled out each time a n equipment

trouble is detected. These reports and logs indicate such

things as equipment affected, nature of the trouble, and

time of failure. When the trouble has been corrected, the

technician ensuring that the correction has been

completed should then ma ke an entry on t he report or in

the log stating so with the date of completion and his or

her signature.

Other locally generat ed logs tha t your shop may

mainta in a re a test equi pment checkout log, to track test

equipment on loa n t o other divisions; a consuma ble

usage log, to track the use of the shops consumable

supplies; a nd a tool accountabi li ty log, to tra ck the tools

issued to individuals.

these forces. Figure 1-7 shows a front cover of

FATHOM.

In the previous paragraphs we have discussed only

a few of the periodicals that are available in the fleet.

You may want to use the technical periodicals to keep

up to date with any changes that may occur to policy or

equipment configuration. However, remember, that

most periodicals are for information purposes only and

do not change or supersede policies, directives, or

instructions.

USING SOURCES OF INFORMATION

Use bulletins, instructions, and periodicals to

increase your knowledge of electronics. They are

excellent sources for discovering new techniques in

troubleshooting and testing of equipment, and for

obtaining updates on safety procedures.

You can use individual command logs, such as those

that we mentioned earlier, to keep an accurate history of

equipment performance, and the location of test

equipment.

You can also use the sources of information that we

discussed above as t ra ining aids for new] y reporting

personnel. New personnel can use the sources to bring

themselves up to date on new procedures and

troubleshooting t echniques. In a ddition t hey can use the

1-5


16/70

log books to learn about t he operat ing history of the

equipment they are assigned to maintain.

MAINTAINING SOURCES OF

INFORMATION

S i n c e s o u r c e s o f i n f o r m a t i o n a r e o f g r e a t

importance to every technician, there is a need to

maintain, update, and care for all of them. In the

remainder of this chapter, we will discuss how to carefor the Electronics Technicians primary sources of

information.

SCHEMATICS

Lets begin with the schematics tha t t ook you so

much time to color code when you were in school,

particularly in C school. The instructor for schematics

gave you certain information that you thought would be

valua ble in th e future. You probably put tha t informat ion

on your schematics. After C school, you may have

referred to those schematics during certain repairprocedures. The schematics became good reference

material . If you stil l have the schematics, laminate them

and make them part of your personal, professional

reference library.

Now lets look at the schematics contained in your

technical manuals. The first thing to remember is that

the technical manuals in your shop are for every

technician to use. Do not write on these schematics. If

you do, you will probably confuse you shipmates when

they need to use them. Often, these schematics tend to

tea r a long th e folds. Reinforce these areas w ith clea r

tape. Finally, be sure to fold the schematics neatly back

into the technical manual when you have finished using

them.

SHOP LOGS

Far too often, shop logs become scratch pads or

doodle pads. To ensure that this does not happen with

your shop logs, place them on book shelves when you

have completed your entries into them. Remember,

these logs w ill contain informa tion on equipment history

that shipmates who arrive on board long after you have

transferred may need to use.

PERIODICALS

Periodicals such as the EIB and the SHIPS SAFETY

B U L E T I N should be kept in hard binders in

chronological order. Keep these binders in a bookcase

or shelf in your shop for everyone in the shop to use. As

we mentioned before, these periodicals are filled with

technical and safety information.

INSTRUCTIONS

There are many instructions in the Navy, and to keep

them all in your shop would be an impossibility.However, in many of these instructions, you will find

pertinent information that pertains directly to the ET

world, such a s electronic safety, ha zar dous mat erial

control, and so on. When you come across this

information, copy it and keep it in a binder for reference

in your shop. Remember to keep this binder up to date

as you receive changes to the instructions.

In this chapter we have discussed some of the

reports, logs, and publications that will be helpful to you

in your everyday job as a technician. You now have the

responsibility to apply this information and to enhance

your administrative skills. In the next chapter you will

learn about the technical administration aspects of your

job as an Electronics Technician.

17/70

CHAPTER 2

TECHNICAL ADMINISTRATION

Technical administration is basically the filling out

of paperwork required to complete a task. Whether the

task is maintenance or repair in nature, it is not fully

completed until all documenting paperwork has beenfinalized. You, as the technician, are responsible for

ensuring that all paperwork is completed for each task

you are assigned.

THE MAINTENANCE DATA SYSTEM

(MDS)

The Maint enance Da ta Syst em (MDS) provides a

means of recording ma intenance actions in substant ial

detail. This allows a variety of information concerning

these actions and the performance of equipment

involved to be retrieved. (In older documents, you may

see the system refereed to as MDCS.) One of the major

objectives of the MDS is to provide the capability of

reporting configuration changes. In the following

para graphs, we w ill describe MDS subsystems that you

will use frequently.

MAINTENANCE DATA SYSTEM

(MDS) FORMS

In the following paragraphs we will briefly discuss

the MDS forms tha t you a s a n ET are most likely to come

across in your daily routine. For more in-depth

information on the MDS forms, we recommend that you

2-1

MDS have been discussed in other training manuals, we

will not cover them here.

Ships Maintenance ActionForm-OPNAV 4790/2K

This form, shown in figure 2-1, is the primary

maintenance form. It is used by maintenance personnel

to report (1) deferred maintenance actions and (2) all

completed maintenance actions (including previously

deferred actions).

The OPNAV 47902K contains six sections that

require entries, depending on the type of maintenance

action being reported. The form is printed on paper that

does not require carbon to make multiple copies.Whenever you make an entry on this form, print the

information, using all CAPITAL letters. Be sure the

information is legible and inserted within the tic

marks. If you make an error, line it out using a single

line and enter the correct information.

Supplemental Form-OPNAV 4790/2L

This form, illustrated in figure 2-2, is used to

provide amplifying information for a maintenance

a ction report ed on a 2K form. For example, you may

include on the 2L information from drawings, listings,associated parts placement, part labels, and the like, for

use by a repair activity.

A conf igurat ion change occurs whenever a

maintenance action results in the following situations:

1.

2.

3.

Addition or installation of any new equipment.

Deletion or removal of any installed equipment.

Replacement or exchange of any equipment. A

replacement or exchange is reported as the

remova l o f an ins ta l l ed equ ipment and

installation of a new equipment.

4.

5.

6.

Modification of any installed equipment. A

modification results from a maintenance action

CURRENT SHIPS MAINTENANCEPROJ ECT (CSMP)

The CSMP is an a dministrat ive system tha t provides

the command and work center with the management

data needed for the systematic accomplishment of repair

and alteration of ships hull, installed equipment, andma terial . It identif ies at an y one time the backlog of

deferred maintenance for each work center. The MDS

provides the mean s for gat hering this information. If the

informa tion provided is not a ccura te or up-to-da te or is

improperly used by supervisors or maintenance

technicians, the CSMP system is worthless.

The usefulness of the MDS depends upon your

accuracy, thoroughness, and timeliness in reporting

information. The MDS is a system in which potential

benefits are directly proportional to the efforts applied.

Programs for improving reliability, maintainability, and

logistic support of fleet equipment depend on how

conscientiously you adhere to reporting procedures.

PLANNED MAINTENANCE SYSTEM (PMS)

The P lanned Ma intenan ce System provides each

command with a simple standard means for planning,

scheduling, controlling, and performing planned

maintenance of all equipment. PMS maintenance

actions are the minimum required to maintain the

equipment in a fully operable condition. Maintenance

procedures are contained on cards called maintenancerequirement cards (MRCs).

Maintenance Requirement Cards (MRCs)

The MRCs provide deta i led information for

performing preventive maintenance. They state exactly

CHAPTER 3

LOGISTICS

As an Electronics Technician, you will definitely be

involved with the supply department in getting the exact

items you need to complete your tasks. To work

effectively and smoothly with the supply department,

you must understand how to use the supply system. This

chapter should help you understand the overall

operation of the system.

NAVAL SUPPLY SYSTEMS COMMAND

The Naval Supply Systems Command (NAVSUP-

SYSC OM) contr ols t he procurement of ma terials a nd

services throughout the Department of the Navy. I t

combines into one overall system inventory managers,

distribution activities, and other activities that areresponsible for providing responsive and efficient

material support to the operating forces of the Navy.

INVENTORY MANAGERS

Navy inventory managers have the pr imary

responsibi l i ty for managing assigned groups or

cat egories of items of supply. The prima ry fu nction of

an inventory manager is to balance parts required and

parts available so that Navy f leet and shore activities

receive effective and efficient support. Navy inventory

m anag e r s i nc l ud e s y s te m s c om m and s , p r o j e c tmanagers, bureaus, offices (including Military Sealift

Command), and inventory control points (ICPs) under

the comma nd of NAVSUP SYSCOM.

INVENTORY CONTROL POINTS

(ICPs)

Ea ch ICP ma na ges one or more types of ma terial

held at stock points in a distribution system. The ICPs

position materials at stock points, maintain inventory

control through an extensive stock reporting system, and

provide technical assistance and cataloging services to

the supply system and its customers.

STOCK POINTS

Stock points are large facilities, such as supply

centers and depots, that stock parts and assemblies for

shipment to requesting commands.

Supply Centers and Depots

Naval supply centers (NSCs) and depots are

command organizations that furnish supply support to

fleet units and shore activities. These stock points are

primarily concerned with procuring, receiving, storing,

issuing, and shipping ma terial. Fleet an d shore activities

send requisitions to the stock points; which, in turn, ship

the ma terial a nd bill the unit for paym ent. The stock

points inform the ICPs of material shipped so the ICPs

can t rack the inventory level and determine when to buy

additional material. Stock points stock Navy, Defense

Logistics Agency, and General Service Administration

cognizance material for issue to supported units.

Supply centers and depots perform similarfunctions, but a t different levels. Supply centers a re

managed by the Naval Supply Systems Command and

support supply depots and other activities that perform

depot functions. Supply depots are commanded by a

fleet command and normally support only local

commands.

Industrial Naval Air Stations

(INASs)

The INASs are primary Navy stock points for

aviation material. These stock points are collocated with

Naval Aviation Depots (NADEPs) and function as

storage and shipment points of aviation cognizance

ma terial. The INASs report tr a nsa ctions of avia tion

material to the cognizant ICP.

MOBILE LOGISTICS SUPPORT

FORCE (MLSF)

The purpose of the MLSF is to release deployed

fleet u nit s from direct dependence on sh ore bases for

supply support. To do this, the MLSF stocks militarily

essential items in high demand by deployed fleet units.

The materials carried by MLSF ships are listed in the

Consoli dat ed Af loat Requi si ti onin g Guid e Overseas

(CARGO), NAVSU P P -4998-A(Atla nt ic) a nd P -4990-P

(Pacific).

GENERAL SERVICES

ADMINISTRATION (GSA)

The General Services Administration controls items

of material th at are common to both milita ry a nd civilian

worlds. Examples of GSA items are paint, paper,

handtools, chalkboards, movie projectors, and the like.

GSA items are stocked at the naval supply centers

located in Norfolk Virginia; and San Diego, California.

DEFENSE LOGISTICS AGENCY (DLA)

The Defense Logistics Agency controls items of

mat erial tha t a re common to a ll the milita ry services but

not to t he civilian world. Exa mples of DLA items a re

fuels a nd bullets. D LA items ar e also stocked a t t he

Norfolk and San Diego naval supply centers.

INTEGRATED NAVY SUPPLY SYSTEM

The Navy supply syst em is an integrated system,

allowing ma terials t o be obta ined usually from more

than one point in the system. In the remainder of this

chapter, we will discuss the Navy supply system in

general, introduce the primary instructions and forms,

and provide a brief description of how to use the system

to get parts and supplies.

The following is a description of how the integrated

Navy Supply System might react to a typical supply

requisition:

USS Ship requisitions cognizance symbol 9N

material from the NSC.

The NSC, a Navy retail stock point, usually

ships the requested material. However, after

screening its stocks, the NSC determines tha t the

requested material is not carried. It then refers

the requisition to the Defense Electronics

Supply Center (DESC), Dayton, the cognizant

inventory manager.

The DESC, Dayton, after researching its master

records and determining that the material is

available at NSC Oakland (a specialized support

point), refers the requisition to NSC, Oakland.

The NSC, Oa kland, issues the ma terial to U SS

ship.

The NSC, Oakland, then makes an issue

transaction report to DESC, Dayton.

The DESC, Dayton, after applying the issue

report to its master record, learns that stock of

the item at NSC, Oakland, is below the required

8.

leve l and i ssues a contrac t to the ABC

Corporation for additional stocks of the item.

The ABC Corporation ships the material to

NSC, Oakland.

The NSC, Oakland, makes a receipt transaction

report to DESC, Dayton.

As you can see, if an item is not a vailable a t t he local

NSC, t he requisition does some tra veling. So it ma y t ake

a little time to get the item you requested.

COORDINATED SHIPBOARD/

SHOREBASED ALLOWANCELIST (COSAL/COSBAL)

The COS AL/COSB AL is t he document t ha t drives

the opera tional a nd supply support for a ship. I t is a

dyna mic document th at changes consta ntly, a s the ships

configuration changes. Each ship in th e U.S. Na vy ha s

its own COSAL or COSBAL tailored specifically to itsmission. The COSAL or COSBAL lists include the

following:

The equipment or components required for the

unit to perform its operational assignments

The repair parts and special tool required for the

opera t ion , overhaul , and repai r o f those

equipments

The miscellaneous portable items necessary for

the care and upkeep of the unit

The COS AL/COS B AL is both a technica l

document and a supply document. I t provides

nomenclature, operating characteristics, specifications,

parts l is t , an d other technical da ta perta ining to al l

insta lled equipment a nd ma chinery. I t also provides

nomenclature and characteristics of the equipage and

tools required to operat e and ma intain t he unit and its

equipment.

No one can predict exactly w hen a circuit card in a n

AN/U RT-23 w ill fail or w hen a bear ing w ill wea r out in

a freshwa ter pump. However, the C OSAL/COSB AL

can help maintenance and supply personnel in a unit to

ma ke an educa ted guess . The COS AL/COS B AL

computers a na lyze the frequency of failures of part s

used aboard units a nd, ba sed on t hese ana lyses, develop

an allowance of repair parts that the supply officer

should stock.

The COS AL/COS B AL is u sed prima rily for t w o

purposes-to identify repair parts (storeroom items) andto determine operating space allowances (equipage).

maintenance and various maintenance-related codes.

The index is published in five parts, sections A through

E. Sections A and B provide a cross-index of all

AP L/AELs listed in P ar t I I. They conta in the sa me

information, but in two slightly dif ferent formats.

Figure 3-2 shows both the A and B indexes. All areas of

information are in the same relative positions, except

that column 8 in Section A listings shifts over to become

column 1 in section B listings.

The bulk of the information you will need to repair

an item covered by COSAL is contained on theappropriate APL or AEL. To identify the appropriate

APL or AEL, you will need to look up either the name

of the equipment in Section A or the use of that

equipment infection B .

equipage associated with mechanical , electrical ,

electronic, and ordnance systems. When an AEL is

written for a system, it identifies the items required to

operat e the sys tem a nd th e repair pa r ts required to

maintain it. The AEL lists specific information for each

item, such a s na me, NSN, unit of issue, quant ity needed,

and quantity allowed on board. AELs are f i led in

numerical sequence by AEL identification number. As a

technician, you should be aware of where all pertinent

AELs can be found.

How to Use the COSAL

Once you become familiar with the indexes, you

will find the COSAL easy to use. The best way to gain

this familiarity is by studying the COSAL for your

command. Read the entries in both the Part I, Section A

and B indexes, then see how they provide across-index

by using th e same entr ies but in a different sequence. As

you study the entries, refer to the introduction for the

meanings of abbreviations that you do not understand.Chapter 4 of the COSAL U se and M ain tenance

Manua l provides instructions for using t he C OSAL.

After you ha ve become fa miliar w ith t he terminology

(chapters 1 through 3), refer to chapter 4 for further

instructions and sample problems.

To be of maximum use to you, the COSAL must be

kept up-to-date at all t imes. Anytime you use the

COSAL, check to be sure it is up-to-date. In the

following paragraphs we will discuss the use of the

COS AL according to S P CC INST 4441.170, the COSAL

ORDERING PARTS, TOOLS, AND

SUPPLIES

There are numerous supply publications that you

should be familiar with to use the supply system to its

full ca pabili ty w hen you requisition par ts a nd t ools.

Although the supply department is responsible for

supplies, you, the technician, need to know how to

identify what is needed, how to write out the request,

and how to report on the use of the supplies. The

publications containing the stock numbers are kept in

the supply department; therefore, to perform your

assigned duties, you must cooperate with supply

personnel.

SUPPLY REQUISITION FORMS

Documenting mater ia l usage and cost data on

maintenance transactions requires a joint effort of the

ships supply a nd ma intena nce personnel. NAVSU P

Form 1250 and DD Form 1348 (discussed in M i l i t a r y

Requirements for Petty Officer Third Class a n d

OPNAVINST 4790.4) a re the pr imary supply

documents used by maintenance personnel. They are

used to requisition parts and materials and to record

material usage and cost data in support of maintenance

ac t ions . Normal ly , ma in tenance personnel a re

responsible for f i l l ing out a nd forw a rding t he supply

forms for materials that they need to do their jobs.

However, supply personnel will provide assistance

whenever difficult or unusual documentation problems

arise.

Some ships have automated supply systems; others

have manual supply systems.

On a nonautomated ship, when a repair par t is

needed before a specif ic ma intena nce action can be

completed, maintenance personnel use NAVSUP Form

1250 to request the issue of the part from the ships

supply department. Supply personnel issue the part if it

is in stock aboard ship. If the part is not in stock supply

uses the information on the form to order the part from

an off-ship source. Nonautoma ted ships a lso use the

NAVSUP Form 1250 to request cha rgeable services.

On an automated ship , when a repair par t is required

to complete a specific maintenance action, maintenance

personnel use DD Form 1348. Chargeable services are

also requisitioned on th e DD Form 1348.

NAVSUP Form 1250 as an invoice for material suppliedto supported units of the submarine forces.

NAVSUP Forms 1250 and 1250-1 were developed

to meet two needs: (1) to improve inventory control

procedures, and (2) to report consumption under the

Maintenance Data System (MDS). Be sure to follow the

general instructions given below whenever you prepare

a NAVSUP Form 1250 or 1250-1:

1. Use a ball-point pen or typewriter.

MILSTRIP requirements, is discussed in M i l i t a r y

Requ i r emen t s f or Pet t y O f f i cer Th i r d C l a ss,

NAVEDTRA 12044. You will be using DD Form 1348s

and your ready reference list of codes (NAVSUP

P ublica tion 409) as y ou order t he items y ou need.

Here are a few reminders as you use the forms:

Prepare the DD Form 1348 by typewriter or ballpoint

pen. Do not use pencil because pencil marks can cause

errors when the requisition is processed through

mark-sensing equipment at shore activities. In preparingrequisitions, you do not need to space the entries within

the tic marks printed on the forms, but you must make

the entries within the proper data blocks. Remember to

use the communication symbol to indicate zero on

MILSTRIP requisitions.

The DD Form 1348 requires the same information

a s the NAVSU P F orm 1250 but in a different order.

DD Form 1348. However, certain items are excluded

from MILSTRIP and are ordered on DD Form 1149

(figure 3-7, included here for your review) unless

otherwise indicated.

SERVMART

A SERVMART is a self-service store operated by a

shore supply activity and is stocked with i tems

frequently required by most departments. Most

SERVMARTs prepare a shopping guide that lists the

i t ems ca r r ied in the SERVMART. Also , mos t

SE RVMARTs provide a shopping list on w hich you can

write the na mes of i tems you wa nt.

The use of sta nda rd forms such a s a DD 1149 ma y

be required at certain supply activities, while at others

no listing of items is required.

If a DD form 1348 is required, make up your

shopping list; then prepare the DD Form 1348. The

money value limit for the shopping list and the

authorized signature are entered in the Remarks

portion of the requisition. The money limit shown is

equal to the total amount of the supporting shopping list,

plus an additional 10 percent to allow for price

At some SERVMARTs credit cards are used.

These cards are issued to activities frequently using the

SERVMART and satis fy the same requirement as the
